Too late probably but propellers have higher effectivity than EDFs. Double???

What current do you expect? Have you calculated it?
www.ecalc.ch → fanCalc
Calculators only get you in the ball park, IF the input is correct.
Without a
watt-meter you are in the dark.

- To trust is good

- To calculate is better

Will get you to say within 10%, IF the input is ok.

- To measure is a must

A watt-meter will more than pay for itself, several times over, your battery, ESC and motor will love you for it. After calculating, always check current when you have a new/changed setup. Will also help you find optimal setup. And it's a great tool for debugging your power train.

In a
true opto controller a BEC is useless. Because it is
optocoupled for complete electrical insulation between controller and ESC.
A
fake opto controller also has no BEC on board, and also no
optocoupler, but is not insulated from the receiver. A bit like calling a car with no brakes an ultra high speed car. Thank you HobbyKrap for creating confusion (once again) with this lovely bit of ... eeeh ... marketing
